Complete unit further relates to the construction technology of the complete unit of the compound in-situ heat regeneration of this novel hot-air microwave.
Background technology
The huge maintenance work amount of Trunk highway highway especially highway, the maintenance project quality of high standard and super large
Maintenance work environment under traffic conditions promotes us to seek a kind of new maintenance method --- and in-situ heat regeneration is a kind of
Using dedicated On-site heat recycling equipment, bituminous paving is heated, milling and then incorporation are certain it is new gather materials, new pitch,
Regenerative agent etc., it is disposable to realize to the old asphalt pavement in the range of the certain depth of surface again through mixing and stirring, paving, the processes such as rolling
Raw technology.
Existing hot reproducer on the spot is primarily present following several respects defect both at home and abroad at present：
(1) road surface is burned, vegetation deterioration, environmental pollution.Road-surface heating machine is mostly red using combustion oil/gas open firing, combustion gas
Outside line heating or extensive style high-power diesel Cycling hot-blast heating mode, bituminous paving heating temperature are not easy to accurately control, Yi Zao
Aging, coking into bituminous paving, the pavement performance on road surface declines after regeneration；The construction high warm flue gas in periphery easily leads to greening
Band, trees it is burned, and with a large amount of toxic blue smoke, pollute environment；
(2) heat penetration is inadequate, and adaptability for working condition is poor.Existing road-surface heating machine heat penetration is deep for 30mm~50mm, leads
Regeneration thickness is caused to be only capable of being confined to 30mm~50mm, the disease of deep layer cannot be handled well, and adaptability for working condition is poor；
(3) interlayer temperature gradient is big, aggregate destructible during milling.According to statistics, bituminous paving top 10mm~20mm is thick
Asphalt material temperature is excessively high (up to 240 DEG C), but the asphalt material temperature at the 30mm~50mm of lower part only has 70 DEG C~80 DEG C, layer
Between temperature gradient it is big, heating it is uneven；And since near-bottom temperature is relatively low, the broken of grading of aggregates in milling process asphalt material is easily caused
Bad (grey material occur) phenomenon, influences reproduction quality；
(4) step heating, layering milling process heat loss are big, time-consuming and laborious costly.
(5) virgin material addition is difficult, and thermal loss is big, and remixing regenerating device frequent intermittent operation influences reproduction quality.It is new at present
The addition of asphalt is mostly completed using transhipment dumper, and can hold together the material of 200mm~300mm thickness after road-surface heating milling
Heap, before transporting dumper filling, more road-surface heating machines and heating milling machine need to move forward 20m~30m, then transport self-unloading
For vehicle again across thick material heap, ride in charging to the hopper of remixing regenerating device, causes remixing regenerating device frequently to stop in material heap
Only operation, thick material heap is driven out to after charging, and then more heaters and heating milling machine retreat playback, resume operation,
There are filling is difficult, interval time is long, heat scatters and disappears the defects of big, regeneration flatness is bad for this filling process；
(6) at present the remixing of hot reproducer on the spot overlay technique remixing process do not add it is a certain proportion of new
Asphalt, and pave to form regeneration zone by remixing after adding in suitable regenerative agent, it is then overlayed on regeneration zone certain
The completely new asphalt of thickness, and real meaning bilayer is not implemented and paves.
